I eat to my meter.
If I get out of bed and my reading is 6 and above I know I dare not have porridge even with coconut oil in so have eggs sausages whatever.
I can't be bothered cooking usually first thing in the morning but a fried egg takes no time and I pull a Polish sausage out the fridge to have with it or I might just have a bullet proof coffee and nothing else.
I'm not rigid with the readings I can give and take to either side depending how I'm feeling.
I've been slowly introducing a little more carbs back into my diet this way.
I do this with evening meal too.
I don't do the three meals a day thing and never have.
Who decided three meals a day was the ideal I don't know.
I'll snack through the day on raw veg cheese things from the fridge but again not rigid in my approach.
My morning readings have been so consistently good of late that I have porridge almost every morning.
